Principle: The OA-TC-ZY compact integrated chilled and hot water unit adopts a patented dual-compressor design. It divides the original single-unit capacity of 36,000–60,000 Btu/h into two stages for startup, reducing the minimum cooling and heating capacity to 18,000–30,000 Btu/h, making it highly suitable for yacht applications. In summer cooling mode, the unit supplies 7°C chilled water for cabin cooling. In winter heating mode, it provides 45°C hot water for cabin heating.
Two-stage startup per unit for reduced inrush current
Integrated control panel, circulation pump, and water replenishment module
Low-noise operation
Digital control with comprehensive protection functions
Corrosion, vibration, and sway resistant design
Patented product - beware of counterfeits
Protection Functions
